New fossils of rhinoceros (rhinocerotidae) from the soan formation (plio-pleistocene) of northern Pakistan

New dental remains discovered from three different localities of the upper siwaliks of northern pakistan are described in this paper. the fossil localities for the present collection include the fluvial sediments exposed near the tatrot village (district jhelum),pabbi hills near the sardhok village (district gujrat),and jari kas (district mirpur,azad jammu and kashmir,pakistan). stratigraphically the fossil locality in the vicinity of tatrot village belongs to the tatrot stage (~3.5-~2.58 ma) of the soan formation,whereas the sardhok and the jari kas belong to the pinjor stage (~2.58-~0.9 ma) of the same formation. the studied specimens are determinated as rhinoceros sp. and rhinoceros aff. r. sondaicus. the fossils of rhinocero sp. are previously known from the upper siwaliks of pakistan and india. however there is no previous record of rhinoceros aff. r. sondaicus in the upper siwaliks of pakistan. the fossil remains of rhinoceros aff. r. sondaicus are reported for the first time from the pinjor stage of the soan formation in pakistan,hence increasing the geographic range of this taxon into pakistan.
